Application filed October 24,1905. Serial No. 284.208'.

To a/ZZ lwhom, it may concern:

Be it known that'I, DAVID W. NUTTALL, a citizen of thel United States,residing at Bayonne, in the county of Hudson and State of New Jersey,have invented new and useful Improvements in Sash-Holders, of which thefollowing is a specification.l

This invention relates to window-sash attachments.

The objects of the invention are to impro ve and simplify theconstruction of such de vices furthermore, to increase their efficiencyin operation and to decrease the expense attending their manufacture.

With the foregoing and other objects in view, which will appear as thedescription proceeds, theinventionresidesinthe combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed as a practical embodiment thereof.

In the accompanying drawings, forming part of this specification, Figure1 is a front elevation showing a Window equipped with the attachments ofthe present invention. Fig. 2 is a front elevation, partly broken away.Fig. 3 is a horizontal section through one of the roller-casings. Fig. 4is a view showing the rear end of one of the roller-casings.

Like reference-numerals indicate corresponding parts in the differentfigures of the drawings.

The reference-numeral 1 indicates a window-frame such as can be placedin houses, buildings, steam or street railway cars, boats, and the like.The frame 1 is constructed without the guard-strips which are usuallyemployed to hold the window-sashes in place. As substitute and impro vedmeans for holding the sashes 2 and 3 in place the side members of theframe 1 are formed with pairs of parallel vertical grooves 4, such asshown in the drawings. Each of the grooves 4 preferably is wedge shapein cross-section. It will be understood that four grooves, such as 4,are employed, two of said grooves serving for the upper sash and theremaining grooves serving for the lower sash. Each of the sashes 2 and 3is formed, preferably, with four dovetail grooves or undercut portion,as shown in Fig. 2. Each of the dovetail grooves extends entirelythrough the sashframe, so as to be open at both ends. Seated in each ofthe dovetail grooves is a casing, such as 5, in which is suitablyjournaled a roller" 6, having'its periphery tapered into wedge shape, soas to fit closelyinto one of the vertical grooves 4 in the window-frame.The roller v6 preferably rests against an integral offset portion 7 onthe front plate of the casing 5. The rearv plate 8 of the' casingpreferably is removably fitted between iianges 9, formed on the frontplate, and is held in position by a machine-screw 10, which extends intoa threaded -socket found in the offset 7 and serves as a journal for theroller 6, as well as a means of retaining the removable rear plate inposition. The rear plate 8 is formed with a slot 11, and the front plateof the casing 5 is formed with a slot 12. The slot 12 preferably iscountersunk, as indicated in Fig. 4.

Extending through the slots 11 and 12and into the sash is a screw 13.Whenever the vertical grooves in the window-frame become worn, so thatthe rollersfit too loosely therein, the screw 13 is loosened and thecasing 5 is moved forward until the rollers 6 fit tightly into thegrooves, after which the screw 13 of each casing 5 is again tightened.Each of the casings 5 is formed with slanting sides, so as to fitclosely into the dovetail grooves in the sash. The slanting sides andthe dovetail grooves therefore aid the screws 13 in holding the casings5 securely in position.

A window equipped with the improved attachments ofthe present inventionworks easily and quickly without friction or rattle. The cumbersomeguide-strips which are usually employed for holding the sashes inposition and which render the removal of the sashes so difficult aredispensed with. The rollers 6 serve effectually to hold the sashes inposition, and when it is desired to remove the sashes it is onlynecessary to loosen the screws 13 and slide the casings 5' backwarduntil the rollers 6 are withdrawn from the wedge-shape grooves 4.

It will be understood that the improvements of this invention can beused as well upon screens, blinds, shades, and the like as upon windows.For this reason the expression sliding member used in the followingclaims is intended to cover any member which is slidable in thewindow-frame.

Changes in the precise embodiment of invention illustrated and describedmay be made within the following claims without departing from thespirit of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is- 1. Thecombination with a windo w-casing provided with a vertically-arrangedgroove, of a Window-frame s1idabl3T mounted in the casing, said framebeing formed with a plurality of horizontally-arranged dovetailedrecesses opening from one surface of the frame and extendingtherethrough from side to side7 a case mounted within the recess andmovable longitudinally thereof to adjust the same relative to thewindow-casing7 a roller carried by said case and arranged to engage thegroove in the casing, and means for securing the case in adjustedposition in the recess relative to the casing.

2. The combination with a window-casing having a vertically-arrangedgroove therein, of a window-frame mounted for sliding mo vement inthecasl'ing, said frame being formed zo with a dovetailed recess openingthrough one surface of the frame and extending therethrough romfside toside, a case shaped to fit the recess and mounted for movement therein,a roller carried by the case and adapted to it within the groove in thecasing, the walls of the case being formed with elongated openings, anda screw engaging said o enings and taking into the frame, whereby DAVIDW. NUTTALL'.
